As presented in the Belle II physics book [1]}, the designed luminosity of SuperKEKB can reach up to \(8\times 10^{35}\text{cm}^{-2}\text{s}^{-1}\) . Thus, the forthcoming Belle II experiment represents the precision frontier of particle physics, which is an ideal platform to perform the correlative study around heavy flavor physics. Obviously, some higher bottomonia can be accessible at Belle II, which may provide valuable hints to construct the bottomonium family.
